The FB_I810_I2C option was added in 74f6ae84b23 ("[PATCH] i810fb: Add
i2c/DDC support"). What do you think about adding this bit from the
commit message as the help text?

Add DDC/I2C support for i810fb. This will allow the driver to get display
information, especially for monitors with fickle timings.

I'm not familiar with this code, so I don't want to do too much
guessing myself. :)
